This rigid cavity board is designed for full fill insulation of cavity walls in both new build and refurbishment projects. It consists of a polyisocyanurate (PIR) core with a low emissivity foil surface and a durable HIPS outer skin, offering a robust solution for thermal wall applications.
With its engineered joint design, the board is typically installed between wall leaves during brick or block construction to help provide consistent insulation across the cavity. The manageable 1200 x 450 mm size aids on-site handling, fitting, and placement in standard cavity dimensions.
